Technical Field

[0001] The present invention relates to an output gear detection device, in particular to an output gear internal and external teeth synchronous detection device with internal teeth applied in the field of gear detection technology. Background Art

[0002] In the modern industrial field, gears are an important transmission component, and their performance and quality have a vital impact on the operating efficiency and service life of the entire mechanical equipment. During the gear processing process, the gears need to be finely inspected, especially gears with internal and external teeth. The phase angles of the internal and external teeth of the gears need to be detected.

[0003] The specification of Chinese invention patent CN202222305440.0 discloses "A device for detecting the phase angle of internal and external teeth of a gear". The device places the internal tooth grooves and internal tooth positioning probes corresponding to the marked holes on the standard part at corresponding positions on the upper platform table. The two internal tooth positioning probes are in full contact with the tooth surfaces of the two symmetrical internal tooth grooves of the standard part respectively, and the external tooth module probe is moved to the external tooth grooves corresponding to the marked holes of the standard part to measure the phase angle.

[0004] When inspecting existing gears with internal teeth, the gear to be inspected needs to undergo complex fixing operations, as well as the tooth groove positioning of the internal and external teeth of the gear in the above-mentioned patent. Since the internal and external teeth of the gear involve multiple groups of different phase angles, the traditional detection method only detects one group, and the phase angle detection of other groups requires the gear state to be re-fixed, which affects the detection accuracy and efficiency of the gear. Summary of the invention

[0005] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is that gear detection requires complex positioning and fixing operations, and the internal and external teeth of the gear involve multiple groups of different phase angles. The traditional detection method only detects one group, which affects the detection accuracy and efficiency of the gear.

[0006] In order to solve the above problems, the present invention provides an output gear with internal teeth and internal and external teeth synchronous detection device, comprising a detection platform, a rotating disk is rotatably connected to the middle of the detection platform, a gear to be tested is placed on the top of the rotating disk, a top pressure cylinder is movably connected to the top of the detection platform, a pressure ring is fixedly connected to the bottom end of the pressure cylinder, and the pressure ring is in contact with the upper surface of the gear to be tested;

[0007] A lifting module is fixedly connected to the back of the detection table, and a detection bracket is fixedly connected to the output end of the lifting module. The detection bracket is bent in a U shape, and the detection bracket is movably connected to the top pressure cylinder. The two ends of the detection bracket are respectively fixedly connected with an internal gear positioning module and an external gear detection module. The internal gear positioning module is plugged into the inner ring of the gear to be tested, and the front and rear ends of the internal gear positioning module are movably connected with positioning ends, and the positioning ends are meshed with the internal teeth of the gear to be tested.

[0009] As a further improvement of the present application, a groove is provided on the lower surface of the pressure ring, and a buffer rubber pad is fixedly connected to the outside of the groove. The buffer rubber pad is made of wear-resistant rubber material. The buffer rubber pad is used to effectively improve the contact effect between the pressure ring and the gear to be measured, thereby effectively improving the pressure and fixation stability of the gear to be measured.

[0010] As a further improvement of the present application, suction cups are equidistantly fixedly connected to the inside of the groove, and the bottom ends of the suction cups extend out of the groove. The suction cups are used to adsorb and fix the gear to be tested, thereby further improving the fixing effect of the gear to be tested. The suction cups are subsequently used to suck up the gear to be tested, making it easier to remove the gear to be tested.

[0011] As a further improvement of the present application, an air groove is provided on the lower surface of the buffer rubber pad, and the suction cup and the air groove are arranged in a colinear manner.

[0012] As another improvement of the present application, calibration modules are fixedly connected to the left and right ends of the testing platform, and a push branch is fixedly connected to the output end of the calibration module. The push branch corresponds to the outer ring of the gear to be tested. After the gear to be tested is placed on the testing platform, the calibration module pushes the push branch to squeeze the outer ring of the gear to be tested, so as to facilitate the precise placement of the gear to be tested in the center position of the rotating disk.

[0017] In summary, the present invention places the gear to be tested in the middle of the rotating disk, and then uses the lifting module to drive the detection bracket to descend, so that the pressure ring at the bottom end of the top pressure cylinder is tightly pressed against the gear to be tested, so that the pressure ring, the gear to be tested and the rotating disk are tightly pressed together and fixed in sequence. The gear fixing method is simple and fast, and the internal tooth positioning module is used to position the tooth groove of the internal teeth of the gear to be tested, and then the external tooth detection module is used to measure the phase angle of the tooth groove of the external teeth, and the pressure sensor is used to collect offset data, which effectively improves the gear detection accuracy and effectively reduces the gear detection time. Subsequently, the rotating disk is used to drive the position of the gear to be tested to rotate and adjust, and a new set of gear phase angles are measured.

DETAILED DESCRIPTION

[0030] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0031] The first implementation method:

[0032] Figure 1-4The invention shows a synchronous detection device for the internal and external teeth of an output gear with internal teeth, comprising a detection platform 1, a rotating disk 101 is rotatably connected to the middle of the detection platform 1, a gear 2 to be detected is placed on the top of the rotating disk 101, a top pressure cylinder 102 is movably connected to the top of the detection platform 1, a pressure ring 103 is fixedly connected to the bottom end of the pressure cylinder 102, the pressure ring 103 is in contact with the upper surface of the gear 2 to be detected, a groove 104 is provided on the lower surface of the pressure ring 103, a buffer rubber pad 105 is fixedly connected to the outside of the groove 104, the buffer rubber pad 105 is made of wear-resistant rubber material, and the buffer rubber pad 105 is effectively improved by the pressure ring 103 and the upper surface of the gear 2 to be detected. The contact effect of the gear 2 to be tested is improved, thereby effectively improving the pressure fixing stability of the gear 2 to be tested. The inside of the groove 104 is equidistantly fixed with a suction cup 106, and the bottom end of the suction cup 106 extends out of the groove 104. The suction cup 106 is used to adsorb and fix the gear 2 to be tested, further improving the fixing effect of the gear 2 to be tested. The suction cup 106 is used to suck up the gear 2 to be tested, which is convenient for the gear 2 to be tested to take out the device. The lower surface of the buffer rubber pad 105 is provided with an air groove 107, and the suction cup 106 and the air groove 107 are arranged in a colinear manner. The air groove 107 is used to communicate with the inside of the groove 104, which is convenient for the discharge of the gas inside the suction cup 106;

[0033] When performing internal and external tooth detection on an output gear with internal teeth, the gear 2 to be tested is placed on the rotating disk 101, and then the pressing cylinder 102 descends to drive the pressing cylinder 102 to squeeze on the upper surface of the gear 2 to be tested, so that the pressing ring 103, the gear 2 to be tested and the rotating disk 101 are tightly pressed together and fixed in sequence, which is convenient for the subsequent rotational position adjustment of the gear 2 to be tested, thereby detecting different groups of phase angles of the gear 2 to be tested. During the pressing process of the pressing ring 103, the buffer rubber pad 105 is used to improve the contact effect between the pressing ring 103 and the gear 2 to be tested to avoid slipping, and then the suction cup 106 is used to adsorb the upper surface of the gear 2 to be tested, which further effectively improves the fixing effect of the gear 2 to be tested. When the pressing cylinder 102 is subsequently raised and restored, the suction cup 106 is used to suck up the gear 2 to be tested, which is convenient for the gear 2 to be tested to leave the rotating disk 101 and the replacement and placement of the gear 2 to be tested.

[0034] Figure 2-6As shown, the back of the detection platform 1 is fixedly connected with a lifting module 3, the output end of the lifting module 3 is fixedly connected with a detection bracket 301, the detection bracket 301 is bent in a U shape, and the detection bracket 301 is movably sleeved with the top pressure cylinder 102, and the two ends of the detection bracket 301 are respectively fixedly connected with an internal gear positioning module 4 and an external gear detection module 5, the internal gear positioning module 4 is plugged with the inner ring of the gear 2 to be tested, and the front and rear ends of the internal gear positioning module 4 are movably connected with a positioning terminal 401, and the positioning terminal 401 is meshed with the internal teeth of the gear 2 to be tested. The rear end of the external gear detection module 5 is fixedly connected with a telescopic module 501, and the output end of the telescopic module 501 is fixedly connected with a telescopic seat block 502, and the interior of the telescopic seat block 502 is hinged with a detection terminal 503, and the detection terminal 503 is meshed with the external teeth of the gear 2 to be tested. A pressure sensor 504 is fixedly connected between the left and right ends of the detection terminal 503 and the detection terminal 503;

[0035] When the internal and external tooth phase angle of the gear 2 to be tested is detected, the positioning end 401 in the internal tooth positioning module 4 extends outward, and the two positioning ends 401 are respectively meshed with the corresponding two internal tooth grooves to position the internal teeth of the gear 2 to be tested, so that the telescopic module 501 of the external tooth detection module 5 pushes the telescopic seat block 502 to move toward the external teeth of the gear, and the detection end 503 in the telescopic seat block 502 is meshed with the tooth groove of the external teeth. When the internal and external tooth phase angle of the gear 2 to be tested is detected, when the detection end 503 is offset, it means that there is a deviation in the phase angle of the gear, and the pressure sensor 504 is used to collect the offset data, that is, the pressure sensor 504 to which the detection end 503 deviates will detect the offset pressure, thereby effectively improving the gear detection accuracy and effectively reducing the gear detection time. Subsequently, the rotating disk 101 is used to drive the position of the gear 2 to be tested to rotate and adjust, and a new set of gear phase angles are measured. All data during the detection process will be recorded in real time, effectively improving the overall gear detection efficiency.

[0036] The second implementation method:

[0037] Compared with the first embodiment, this embodiment mainly adds a calibration module 6 and a push branch 601. The specific newly added structure is as follows, and the remaining structure is consistent with the first embodiment.

[0038] Figure 7-8As shown, the left and right ends of the test platform 1 are fixedly connected with calibration modules 6, and the output end of the calibration module 6 is fixedly connected with a push branch 601, and the push branch 601 corresponds to the outer ring of the gear 2 to be tested. After the gear 2 to be tested is placed on the test platform 1, the calibration module 6 pushes the push branch 601 to squeeze the outer ring of the gear 2 to be tested, so that the gear 2 to be tested is accurately placed in the center position of the rotating disk 101. The push branch 601 is arranged in a Y shape, and the opening angle of the push branch 601 is 90°, so that the push branch 601 can adapt to gears 2 to be tested of different diameters, and effectively improve the adaptability of the detection device;

[0039] After the gear 2 to be tested is placed on the rotating disk 101, the calibration module 6 is used to push the push branch 601 to apply force to the gear 2 to the left and right, so that the gear 2 to be tested is accurately placed in the center position of the rotating disk 101, which facilitates the subsequent pressing ring 103, the gear 2 to be tested and the rotating disk 101 to be tightly pressed and fixed in sequence, effectively improving the accuracy of the position rotation adjustment of the gear 2 to be tested.

[0040] Figure 7-10 As shown, a rotation groove 602 is provided on one side of the push branch 601 close to the gear 2 to be tested, and a guide slide rod 603 is rotatably connected inside the rotation groove 602. The outer ring of the gear 2 to be tested corresponds to the guide slide rod 603 and contacts the outer surface of the guide slide rod 603. The arc surface of the guide slide rod 603 contacts the outer teeth of the gear 2 to be tested, and the contact area is small, thereby effectively reducing the friction between the gear 2 to be tested and the push branch 601. The outside of the guide slide rod 603 is coated with a sliding film 604, which is fixedly connected to the push branch 601 and is made of wear-resistant rubber material. The sliding film 604 is used to contact the guide slide rod The rod 603 is covered to effectively reduce the wear of the gear 2 to be tested and the guide slide rod 603. The end of the guide slide rod 603 close to the calibration module 6 is fixedly connected with a bevel gear 605. The middle part of the push branch 601 is fixedly connected with an adjustment module 606. The output end of the adjustment module 606 is meshed with the bevel gear 605. The cross-section of the guide slide rod 603 is set to be elliptical. When the gear 2 to be tested needs to be rotated and adjusted, the adjustment module 606 drives the bevel gear 605 through meshing to rotate the guide slide rod 603, adjust the contact surface between the guide slide rod 603 and the gear 2 to be tested, and provide space for the rotation of the gear 2 to be tested.

[0041] When the push branch 601 applies left and right forces to the gear 2 to be measured, the outer teeth of the gear 2 to be measured contact the arc surface of the guide slide rod 603, effectively reducing the contact area between the gear 2 to be measured and the push branch 601, and utilizing the smooth effect of the sliding film 604 to effectively reduce the wear between the guide slide rod 603 and the gear 2 to be measured, thereby reducing the friction between the two, facilitating the subsequent rotational position adjustment of the gear 2 to be measured, and driving the meshing bevel gear 605 through the adjustment module 606 to realize the rotation operation of the guide slide rod 603, changing the contact surface between the guide slide rod 603 and the gear 2 to be measured, providing space for the rotation of the gear 2 to be measured, facilitating the rotational position adjustment of the gear 2 to be measured, and facilitating the push branch 601 to continue to maintain the calibration positioning of the gear 2 to be measured.

[0042] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
